OK, I have not been on this site for quite a while have been getting ready for SAS. I just read a couple of threads and found that clifford products are being talked about quite a bit more than when I was researching my build. TRUST ME. Don't have clifford do any machine work for you. Don't buy their cylinder head. I wouldn't even recomend using thier cams. They do not do their own machine work. They don't even manufacture their own headers. All they do is sit in an office and tell people how great their stuff is. I know becaues I bought the whole shootin' match. EFI long block. I don't want to write all night long so I won't go into sortid details. I know that there is a limited market for aftermarket pieces for our beloved engine, but the parts are out there. I would like to give a BIG THUMBS UP! to redline/webber. If you want a fully programable fuel injection system CALL THEM FIRST! Tell them what you want and that you had been warned against clifford. Of course if you want to give your hard earned money to some dude named Larry to use as he pleases for 7-9 months. Go right ahead. If you do order parts from them make sure it is IN STOCK. Don't buy his line of 3-4 weeks. THIS IS ALL FROM MY PERSONAL EXPERIENCE. Take it or leave it.
